ISDL 66-116 KYX series The ISDL indoor units, together with their associated OSA outdoor units, provide a reverse cycle (heat pump) split system air conditioner designed and developed to comply with and exceed AS/NZS 3823. Each system has been successfully tested at 52 C ambient. Page 3 of 17
ISDL 66-116 KYX series Applications These low profile units have been specifically developed for air conditioning of light commercial and residential premises, e.g. offices, motels shops and homes. AIR FLOW SELECTION If the air returning to the indoor coil is regularly expected to be above 50%RH, then the coil face velocity should be limited to be 2.5 m/s or less. High humidity levels can occur in tropical or subtropical conditions, and/or when heavily moisture laden fresh air is introduced. Consideration must always be given to selecting an air flow and face velocity that avoids water carry-over problems. Applications using full or high proportions of fresh air should be referred to your nearest temperzone sales office to establish the correct selection of units. FEATURES Refrigerant R410A Each complete system uses refrigerant R410A which has zero ozone depletion potential. User Friendly The air conditioning system is available with an optional SAT-3 or TZT-100 Controller which is wired to the Indoor or Outdoor unit. These thermostats have been designed to maintain a high level of comfort for room occupants. Emphasis has been placed on providing controls that are easy to use despite the sophisticated microprocessor system that runs it. Use of the Auto and Timer function settings allows you to set it and forget it. Efficient Indoor units include a high efficiency electronically commutated (EC) motor. Part load operation at low loads (75% airflow equates to 55% power use) using temperzone algorithms. Each outdoor unit incorporates a high efficiency compressor. Heat exchange coils use inner grooved (rifled) tube for better heat transfer. Performance The OSA 116 digital scroll compressor technology can provide close comfort control of the room temperature. A dynamically balanced forward curved fan with a multi-speed EC motor enables fine tuning of the indoor unit to match the supply air requirements. These EC motor fans have a fully integrated speed control that enables soft starting. Fan speed can be stepped to your own requirements or continuously variable using a 0 10V DC control signal. The system includes a temperature sensing head pressure control which enables the system to compensate for outdoor ambient temperatures below 20 C on cooling cycle, and above 15 C on heating cycle. Low Profile. The indoor units have a low 267 mm height making them ideal for small ceiling spaces. Quiet Each integral high efficiency EC motor can vary from zero to full speed. This allows slow ramp up with no sudden noise change. The outdoor units coil design permits low fan speeds and hence low noise levels. The compressor is isolated in a built-in, insulated compartment to minimise noise. The indoor unit is also insulated for noise attenuation. Page 4 of 17
ISDL 66, 87, 116 Slimline The compact up-right design of the outdoor units requires only a 100 mm gap on the coil side where installation is against a wall. Their slimline cabinets are particularly practical where there is restricted space, e.g. side access pathways, balconies, narrow ledges, etc. The unit is free standing, but can be fitted on a wall using the optional wall mounting brackets. Durable Both indoor and outdoor coil fins are epoxy coated for extra protection in corrosive environments, e.g. salt laden sea air. Each outdoor unit s cabinet is constructed from high grade galvanised steel - polyester powder coated (grey) for all weather protection (IP 44). External fasteners are stainless steel. Heat exchange coils comprise aluminium corrugated plate fins on mechanically expanded rifled copper tube. Each indoor unit s cabinet is constructed from high grade galvanised steel and includes a plastic drain tray for complete corrosion resistance. OSA 116 coil is protected with louvred anti-hail guards. Serviceable To enable a thorough cleanse, the indoor units drain tray is removeable. Control Option Commissioning is made easier when the EC motor to be controlled variably (within a restricted range) by a 0 10 volt DC signal that can be supplied either by a BMS system, a sophisticated controller or temperzone s optional TZT-100 Controller. Compatiblity The supply and return air spigots on the indoor unit have been designed to fit standard flexible ducting. Alternatively they can easily be removed for attaching rigid ducting. Self Diagnostics The Outdoor Unit Controller (UC8) has a LED display to indicate faults and running conditions. A non-specific fault indicator is included for interface to external systems via the optional relay board. Zone Control ISDL 116KYX versions, if supplied with SAT-3 controller, can be fitted with the optional Zone Control kit which allows up to 6 zone dampers to be switched from the SAT-3 wall control. Standard damper motors, 24 volt ac, can be used with drive open/drive close. Insulation Closed cell foam insulation has been used in the indoor units cabinet to ensure no particles are introduced into the air stream. The insulation is foil faced and meets fire test standards AS 1530.3 (1999) and BS 476 parts 6 & 7. Page 5 of 17

Soft Starter for lowering starting current (OSA 116RKSG only). Indoor Unit: REFRIGERATION PIPING Maximum line length is 40m for OSA 66/87 and 60m for OSA 116. Max. height separations between units are: Outdoor unit above indoor unit: 20m Outdoor unit below indoor unit: 20m. Each OSA unit is shipped from the factory with a charge of HFC-410A (R410A) refrigerant sufficient for a 10m line length. Liquid and suction service valves are provided. The matched indoor unit is shipped with a holding charge of nitrogen. Both units have brazed pipe connections. 1. temperzone SAT-3 Controller or TZT-100 Controller. 2. Six Zone Control kit for SAT-3 (ISDL 116 only). 3. Spring mounting kit. 4. Filter - EU2/G2 rated. SAFETY FEATURES 1. HP and loss of refrigerant protection. 2. Anti-rapid cycle timer and internal overload for compressor protection. 3. Circuit breaker control circuits. 4. Time-and-temperature controlled electronic de-ice switch ensures icing up of the outdoor coil during heating cycle is kept to a minimum. WIRING The electrical supply required (including voltage fluctuation limits) is: OSA 66/87/116 RKS: 1 phase 200 252 V a.c. 50 Hz with neutral and earth. OSA 116 RKT: 3 phase 342 436 V a.c. 50 Hz with neutral and earth. A control panel, located in each outdoor unit, is fully wired ready to accept the main power supply.
